I believe most clues have led to the concensus being, yes, it will have the multi-link suspension. That's fine by me, because it'll spend more time on the road than the 1320, and with advancements in cars like the Z06 and ZR1, there is programming out there to control the suspension and engine/tranny to where settings can be changed to accomodate 1320 runs or around a road course. Whether or not these technologies will be available in these cars is another matter though. The only concern I have is its durability.

I haven't read anything about Zeta in a while, so my memory fails me. But look up the Holden Commodore; Or the Vauxhall VXR8. Those both ride on Zeta....and should mention something about the suspension details like this.
